        • Wire Race Bearings

          • Wire Race Bearings: compact, highly durable, individual

            The Franke principle delivers maximum design freedom

            In our Wire Race Bearings, the rolling process does not take place directly between the rolling element and the mating structure, and instead with low friction on the race rings. You receive maximum design freedom thanks to their compact and highly durable 4-point contact. You are at liberty to choose whichever material, geometry, size, bore pattern, gear and sealing you require.

              • Bearing Elements

                  • Maximum possible integration capacity

                                                  • Leading along the entire line

                                                    Franke Linear Systems are used across a broad variety of different industries – among them the food and packaging sectors. In many cases, their smooth and quiet running is essential to achieve trouble-free operation.

                                                      • Camera sliders

                                                      • Requirements

                                                        Numerous so-called slider systems are available on the market to move video cameras. The system by the firm SlideShot from Great Britain is a recent addition, which uses Franke linear guides. These systems have the following requirements: smooth and quiet operation, homogeneous movement and low weight.

                                                      • Requirements

                                                        Cutting with a water jet calls for exact and rapid movements of the cutting head above the work piece to create even and smooth edges and to travel along even more complex geometries.

                                                        Franke linear motor module FTH Drive with integrated direct drive.

                                                        Advantages

                                                        Lightweight aluminium design for low weight and dynamic movement. The linear motor is integrated in the rail profile. This makes the module extremely flat and ensures it requires very little mounting space. The aluminium body and the non-corrosive running bars make the system insensitive to moisture.

                                                      • Food packaging

                                                      • Requirements

                                                        The packaging machine works at high speeds. The linear guides used here must be resistant to aggressive media (e.g. salt, sugar, spray water). The machine has stroke lengths of 1500mm to 2100mm. The average mileage of the packaging machine is 30,000km per year.

                                                        Advantages

                                                        The aluminium roller guides FDA enable speeds of up to 10m/s. The stroke lengths are infinitely variable. Central lubrication on the cassette achieves a high service life and substantial mileage. Grease nipples fitted to the front allow for convenient lubricant replenishment while the guides are fitted.

                                                      • Cheese production

                                                      • Requirements

                                                        A linear guide is to be used to hold a cheese wheel in place for the subsequent cutting process. The guides must satisfy the hygienic requirements for use in the food industry. There must be no leakage of lubricant. The system has relatively weak motorization.

                                                        Solution

                                                        The aluminium roller guides in the system FDA25 with tracks from the series FDC25.

                                                        Advantages

                                                        The Franke aluminium roller guide operates cleanly and maintenance-free thanks to the food industry-compatible non-corrosive design. It comes with food industry lubrication. The guide can be set to the desired low slide resistance using a grub screw fitted to the side of the cassette. This is used to reduce the drive power applied to the guide.

                                                      • Requirements

                                                        Bonding points to bond the mattresses are positioned in the center of the gantry. The guides are used to travel to the gantry along the x and y axes. The assembly surfaces of the guides are not processed in order to save costs.

                                                        Solution

                                                        The aluminium roller guide FDA25 in a length of 2000mm.

                                                        Advantages

                                                        The guide unit, motorized by a toothed belt, travels at a speed of 50m/min. The guide is fitted directly to the unprocessed aluminium substructure. This involves mounting aluminium on aluminium, which means there is no bi-metal effect in the event of temperature fluctuations. This cost efficient solution makes the system competitive. Customers achieve maximum drive culture using the aluminium roller guide. The system preload is infinitely variable to suit the requirements.

                                                      • Requirements

                                                        Machine units in a packaging machine need to travel quickly and safely. High clock rates necessitate dynamic movement patterns. Two units are moved on one module.

                                                        Solution

                                                        Franke linear motor module FTH Drive with two motors.

                                                         

                                                        Advantages

                                                        Franke linear motor modules in type FTH Drive come with linear motors fitted to the guide rails. This engineering reduces the mounting space and enables compact designs. The module bodies are made of aluminium and harmonize perfectly with the aluminium profiles used to assemble the machine. Two motors, controlled separately, ensure highly dynamic movement.

                                                      • Dental X-ray device

                                                      • Requirements

                                                        The linear guide is used in the secondary panel of the dental X-ray device. The purpose of the panel is to enable exact X-ray imaging. Here it is important that the unit travels without any oscillation whatsoever. The linear guide must run easily and smoothly.

                                                        Solution

                                                        The Franke roller guide FDL12 is integrated directly in the customized carriage mount. A lateral grub screw is used to set the slide resistance and hence the stiffness of the entire system. This guarantees movement without any oscillation whatsoever.

                                                        Advantages

                                                        The guide FDZ12 runs evenly, quietly and cleanly. The elevated preload (0.6 to 0.8N) ensures that the secondary panel travels free from oscillation. The guide comes with lifetime lubrication. The sealed, single-row ball bearings mean that no lubricant can leak to the outside.
